A big-rig driver hauling cream and other dairy products crashed on Byron Highway in eastern Contra Costa County on Thursday when he reached for a soda and lost control, the California Highway Patrol said.

The crash happened about 5:15 a.m. as the driver was heading north on the highway near Camino Diablo Road in Byron, said CHP Officer John Fransen.

The truck ran off the highway, crashed into a telephone pole and overturned, spilling containers of cream used to make ice cream into a nearby field, Fransen said.
